What are the causes of global warming and what harm will it do?

Now the global temperature is getting warmer. In fact, warming the temperature is not a good thing for the earth, it will bring some serious consequences to the earth. Then let's use the knowledge of constellations to reveal the causes of global warming. What are the consequences? What are the causes of global warming? Now the global temperature is getting warmer. In fact, warming the temperature is not a good thing for the earth, it will bring some serious consequences to the earth. Then let's use constellation knowledge to reveal the causes of global warming. What are the consequences? Global warming is a phenomenon related to nature, which is due to the continuous accumulation of greenhouse effect, resulting in the imbalance of energy absorbed and discharged by the geo-atmospheric system, and the continuous accumulation of energy in the geo-atmospheric system, leading to rising temperature and global warming. Because people burn fossil fuels, such as oil and coal. Or cutting down and burning down forests will produce a lot of carbon dioxide, that is, greenhouse gases, which have a strong permeability to visible light emitted by the sun, a strong absorption to long-wave radiation emitted by the earth, and a strong absorption of infrared radiation from the ground, leading to an increase in the temperature of the earth, that is, the greenhouse effect. Global warming will redistribute global precipitation, melt glaciers and frozen soil and raise sea level, which will not only endanger the balance of natural ecosystems, but also threaten human survival. On the other hand, due to the greenhouse gas emissions from the land, the temperature in the mainland rises and the temperature difference with the ocean becomes smaller. Recently, the airflow has slowed down, and the smog can't be blown away in a short time, which has led to an increase in smog weather in many cities, affecting human health. Measures such as car restrictions and production suspension have only short-term and local effects, and cannot fundamentally change climate warming and smog pollution. What harm will global warming do to the environment? 1. Glacier melting (mainly the influence of continental glacier melting) will make the global sea level rise, threatening low-altitude coastal countries or economically developed regions. 2. It may increase the frequency of extreme weather, such as drought, flood and extreme temperature. , affecting biological survival, precipitation may decrease in low latitudes, which has a great impact on agriculture. 3. Affect the global ecosystem, change the ecological environment, and speed up the extinction. The harm of global warming to human beings is 1, and the rising temperature will provide kinetic energy to the air and ocean, causing disasters such as super typhoon and tsunami. Every year, there are more and more disasters. At the same time, typhoons and tsunamis will destroy buildings, threaten human life safety, bring mudslides and landslides, and cause great hidden dangers to mankind. 2. The rising temperature will also lead to a sharp reduction in grain and feed production in inland areas, and food and meat will be in short supply. 3. As the temperature rises, icebergs don't melt as fast as they do, so that icebergs no longer pile up and we have no fresh water to drink. The natural food chain is gradually broken by the rising temperature. 5. The increase of carbon dioxide content in the atmosphere will also lead to the increase of carbon dioxide content in the ocean, which will carbonate the ocean, kill microorganisms, break the marine food chain and kill a large number of marine life. 6. Rising temperature will also make many invertebrates wake up from hibernation, and then these insects miss the opportunity to prey and die in large numbers. Because insects wake up early, they eat many forests and crops. 7. At the same time, the rise of temperature will also have an impact on human function, the probability of getting sick will be higher and higher, and various physiological diseases will spread rapidly. 8. Rising temperatures, melting glaciers and rising sea levels have caused the loss of coastal mudflats, mangroves, coral reefs and other ecological groups, coastal erosion, seawater intrusion into coastal fresh groundwater layers, and coastal land salinization. It leads to the imbalance of natural ecological environment in coastal areas, estuaries and bays, and brings disasters to coastal ecological environment. 9. The water area has increased. Water evaporation is also more, the rainy season is prolonged, and floods are more frequent. The chances of being flooded increase, the degree and severity of being affected by heavy rain increase, and the life of reservoir dams is shortened.
